ABSTRACT

An alternative method essentially based on a simple reduction procedure and inverse Fourier sine transform technique is employed here to reinvestigate the three-dimensional problem of in-coming surface water waves against a rigid vertical cliff in an ocean of infinite depth. Assuming linear theory, analytical expressions for the velocity potentials are obtained here by ignoring the effect of surface tension and also by considering the effect of surface tension at the free surface. Various known results are recovered as special cases.
